System Test Plan update• P2 and RPC testsSystem Test Programme– Pole 2 return to service - temporary interface confirmation (4)– HAY & BEN RPC commissioning -manual control tests (12 HAY, 5 BEN)– Some restrictions on P2 capacity ( 7 tests). Remainder of tests P2 available.• P3 energisation and low power tests– P3 open line test manual only– Station under voltage and under frequency ride through tests bought forwardfrom medium power test section• P3 medium and high power tests– P2 energisation tests with P3 on load– Electrode line staged fault testsGreg Spence5
